Kernel in windows

The VM only runs when you need it. Moreover, it is not completely isolated like a traditional VM. You can very easily interact with the rest of the Windows system, including files in your Windows drives using WSL v2. It is not an isolated VM but an integrated part of Windows How does it achieve that? With WSL v1, accessing files and directories on your Windows guests was trivial.

Your Linux userland is just an app on Windows, so it can read and write files originally belonging to the native OS pretty easily. With WSL v2, you have a VM running with its virtual harddisk formatted with ext4, of course and if we want a similar experience like that of WSL v1, we need some extra mechanisms. Enter Plan 9.

While it is unlikely that you will ever find it running in production, it still lives on as various other operating systems adopt interesting ideas that are incubated in it, including the 9P Protocol for a file server.

This allows you to access Windows 10 files natively inside your WSL environment. This means that SMR allows you to store more data per inch. Read on to find out more about this new hard drive technology and its implications. Instead of a compatibility layer, WSL2 relies on the virtualization of a complete Linux kernel.

This means that even complex applications such as Docker can be operated in the Linux environment.

What is a kernel? Structure of a kernel A kernel is always built the same way and consists of several layers : The deepest layer is the interface with hardware processors, memory, and devices , which manages network controllers and PCI express controllers, for example.

On top of that is the memory management , which entails distributing RAM including the virtual main memory. Then comes process management scheduler , which is responsible for time management and makes multitasking possible.

The next layer contains device management. The highest layer is the file system. Process A kernel is central to all layers, from system hardware to application software. What is a kernel in a computer program? How does a kernel work? The functions of the kernel vary among its five layers, from processor management to device management. The highest layer cannot access machines, and instead is responsible for interfacing with software. Application programs run separately from the kernel in the operating system and merely draw on its functions.

Several processes can run simultaneously thanks to the multitasking kernel. As these are two different spaces in the memory, so communication between them is a bit slower. There are certain instructions that need to be executed by Kernel only. For example, memory management should be done in Kernel-Mode only. Monolithic Kernels are those Kernels where the user services and the kernel services are implemented in the same memory space i. By doing so, the size of the Kernel is increased and this, in turn, increases the size of the Operating System.

As there is no separate User Space and Kernel Space, so the execution of the process will be faster in Monolithic Kernels. A Microkernel is different from Monolithic kernel because in a Microkernel, the user services and kernel services are implemented into different spaces i. As we are using User Space and Kernel Space separately, so it reduces the size of the Kernel and this, in turn, reduces the size of Operating System.

As we are using different spaces for user services and kernel service, so the communication between application and services is done with the help of message parsing and this, in turn, reduces the speed of execution. It makes the use of the speed of Monolithic Kernel and the modularity of Microkernel. Hybrid kernels are micro kernels that have some "non-essential" code in kernel-space in order for the code to run more quickly than it would be in user-space.

It basically manages operations of memory and CPU time. It is core component of an operating system. Kernel acts as a bridge between applications and data processing performed at hardware level using inter-process communication and system calls. Kernel loads first into memory when an operating system is loaded and remains into memory until operating system is shut down again. It is responsible for various tasks such as disk management, task management, and memory management.

It decides which process should be allocated to processor to execute and which process should be kept in main memory to execute. It basically acts as an interface between user applications and hardware. The major aim of kernel is to manage communication between software i. Objectives of Kernel : To establish communication between user level application and hardware.

To decide state of incoming processes. To control disk management.
